Editsub vs Subvideo.ai

EditSub is a web-based subtitle editor and management tool for changing subtitle text, adjusting timing, translating subtitles and converting formats. It works with SRT, VTT, SBV, SUB, ASS and SSA files, and exports SRT and VTT. Its AI translation supports more than 100 languages. Local audio or video files up to 10 minutes can be transcribed free without logging in; longer files and translation require credits. The AI co-pilot can flag reading-speed, timing, overlap, gap, line-length and transcription issues, and can fix or rewrite cues. Timing tools include frame-accurate adjustment, batch shifting, waveform synchronization and real-time preview. Video-to-subtitle accepts listed audio and video formats, with a maximum media size of 3072 MB; subtitle uploads are limited to 10 MB. The free plan includes 10 subtitle files. Pro is listed at $4 a year, billed $48 per year, with 1,500 credits per month.

Subvideo.ai creates subtitles from audio or video and provides a browser-based studio for editing text, timing, styling, and synchronization. Users can translate subtitles, identify speakers, and export subtitle files or video with captions burned in. Free subtitle downloads include SRT, ASS, VTT, SBV, and TXT. A voiceover workflow lets users choose a voice and language, adjust speed and pitch, and export an audio track or rendered video. The site presents workflows for YouTube, TikTok, Netflix, Premiere Pro, Final Cut Pro, and DaVinci Resolve. It supports common audio and video uploads, including MP3, WAV, MP4, MOV, and WEBM. Guest mode allows one upload per day; a free account allows three and includes voiceover for media projects. Ultimate costs $9.99 a month and adds multiple-file uploads, priority processing and support, and burn-in without the free watermark. File and processing limits apply to every plan.
